NYC May 7 Low Temp: Will Fifty Degrees Hold?

The 50-51°F outcome for New York City’s lowest temperature on May 7 is sitting at 78.5% implied probability this morning. That conviction didn’t build gradually. The contract opened near 24 cents and has surged more than 46% in the last 24 hours alone. Something in the forecast data locked in, and traders followed fast.

This is a same-day weather resolution market. The answer will be known before noon on May 7, 2026. Right now, the market is telling you that NYC’s overnight low is almost certainly landing in the 50-51°F range. Here’s what the measurements are telling us: current atmospheric conditions are consistent with a mild early May night, not a cold snap and not a warm outlier.

How the Contract Resolves: The Fifty-to-Fifty-One Degree Band

The contract pays out if New York City’s official lowest temperature on May 7 falls between 50°F and 51°F inclusive. Resolution is based on verified meteorological reporting for the date. A YES holder collects if the measured low lands in that two-degree band. A NO holder collects if the low settles anywhere else, whether colder or warmer.

• YES (50-51°F): $0.79 per share, 78.5% implied probability
• NO (all other outcomes): $0.22 per share, 21.5% implied probability

The NO side covers a wide range of alternatives: 48-49°F, 52-53°F, 54-55°F, even 60°F or above. That spread matters. The NO position isn’t betting on one specific miss. It’s betting the actual low falls anywhere outside that narrow 50-51°F window. Weather forecasts carry real uncertainty at the two-degree precision level, and that’s exactly what the 21.5% NO price is capturing.

Momentum and Market Signals: A Forty-Six Percent Run in Twenty-Four Hours

The momentum composite here is striking. A 20.5% one-hour gain, a 46.5% 24-hour run, and a trend score of 87.94 represent a single coordinated signal. The most likely driver is a forecast update that narrowed the expected low range and aligned closely with the 50-51°F band. When NWS or a major weather model tightens a forecast this close to resolution, fast-moving short-duration markets like this one reprice immediately.

Total contract volume sits at $14,190, with $8,701 of that trading in the last 24 hours. Liquidity is $30,977. Volume under $1 million means this market can move sharply on a single updated forecast or a cluster of trades. The price action already demonstrated that today. One data update and the contract shifted more than 46 cents in probability terms overnight.

• The 1-hour gain of 20.5% and the 24-hour gain of 46.5% together reflect a single repricing event, most likely a tightening NWS forecast for the overnight low.
• Liquidity of $30,977 is thin relative to major prediction markets. A few large trades or one more forecast update could move the price significantly before the noon resolution.
• Trader sentiment is strongly bullish at 78.5% YES versus 21.5% NO, consistent with a market that has largely priced in the 50-51°F outcome.
• The 24-hour volume of $8,701 represents more than 60% of total volume, confirming the bulk of the conviction formed in the final hours before resolution.
• Open interest is listed at $0, which suggests most positions have been established today and the market is in final-approach mode.

Lines Analysis: What the Forecast Data Supports

Early May in New York City typically sees overnight lows in the upper 40s to low 50s. A 50-51°F reading is squarely within the historical norm for this date. When the NWS forecast aligns with climatological averages and the synoptic pattern shows no cold front or warm surge pushing through, the 50-51°F band becomes the natural target. The market’s rapid convergence on 78.5% reflects forecasters and traders reaching the same conclusion simultaneously.

The NO scenario requires the actual low to deviate meaningfully from current forecast guidance. That means either a colder-than-expected overnight (a front arriving faster or stronger than modeled) or a warmer-than-expected low (a southerly flow holding temperatures above 52°F). Two-degree precision is hard. NWS forecasts at this range carry a margin of error that keeps the NO position relevant even at 21.5%.

• Any NWS forecast revision issued before noon that shifts the expected low above 52°F or below 50°F would reprice this contract sharply toward NO.
• An actual observed low reported at 52°F or above by Central Park weather station would resolve NO regardless of forecast consensus.
• Sustained southerly winds overnight could push the low warmer than forecast, making the 52-53°F band a live alternative outcome.
• A faster-moving cold front passage could pull the low into the 48-49°F range, also resolving NO.
• Official resolution timing at noon means there is almost no window for additional forecast revisions to change the outcome before settlement.

With $14,190 in total volume, this market is not deep. But the directional signal is clear. The data and the forecast are aligned. The 78.5% YES price reflects genuine meteorological consensus, not just trader momentum. The market is pricing uncertainty, not science, and right now, the science says 50-51°F.

LINES VERDICT

Forecast Aligned, Market Confirmed

The rapid repricing toward 78.5% YES reflects a forecast convergence, not a guess. NYC’s May 7 low is tracking directly into the 50-51°F band based on current NWS guidance and historical pattern, and this market has priced that outcome with high confidence.

What the market says: 78.5% implies a strong but not certain call on the 50-51°F band. With resolution at noon on May 7, 2026, there is almost no time left for forecast revisions to shift the outcome. The thin volume means any last-minute trade cluster could still move the price.

Key unknown: The single variable that would reprice this contract is a final NWS update issued before noon placing the expected low above 52°F or below 50°F. That window is nearly closed.

Scientific Context: Early May Temperature Patterns in New York City

New York City’s average low temperature in early May hovers around 50-52°F, based on Central Park long-term climatological data. A reading in the 50-51°F range on May 7 would be entirely normal, not an outlier in either direction. The market’s convergence on this outcome is consistent with both the seasonal baseline and the current synoptic forecast pattern. The data doesn’t care about the politics of prediction markets. A May overnight low in New York City either lands in a two-degree window or it doesn’t, and the measurements will settle the question before lunch.

Frequently Asked Questions

• What does 78.5% probability mean here? The 78.5% YES price means the market assigns roughly a four-in-five chance that NYC’s official low on May 7 falls in the 50-51°F range. It is a consensus estimate, not a guarantee.
• What does the NO contract pay on? The NO position at $0.22 pays out if the actual May 7 low in New York City lands at any temperature outside 50-51°F, including warmer outcomes above 52°F or colder outcomes below 50°F.
• What data release or event would move this price? A National Weather Service forecast update issued before noon on May 7 that shifts the expected overnight low above 52°F or below 50°F would reprice this contract sharply. Actual observed temperature reports from Central Park would resolve it outright.
• When does this contract resolve? Resolution is set for noon on May 7, 2026. The market closes at that timestamp, and the outcome is based on the official measured low for the day.
• Is the $14,190 volume reliable? Total volume of $14,190 is thin. Liquidity of $30,977 means the market can absorb modest trades, but a single large position or a forecast update could move the price significantly before noon resolution.
